I have created one flow to send message from Power Automate to WhatsApp through WhatsApp cloud API, but I am encountering one error "{"error":{"message":"(#100) The parameter messaging_product is required.","type":"OAuthException","code":100,"fbtrace_id":"abcdefg"}}" .
To resolve this issue I mapped parameters multiple time, recreated flow but this error is still unsolved.
Any help appreciated.
